9 in. Heavy-Duty Auger for Tractor 3-Point Post Hole Diggers

The 9 in. Heavy-duty auger with 2 in. Round Shafts are for use with tractor-mounted 3-point post hole diggers and skid steers to make fence installation easier. The heavy-duty auger attaches to most 2 in. gearbox output shafts. This auger features thick double-flighting with more extensive welding and a reinforced input shaft collar. for tractors and skid steers with 2 in. round output shafts, a 9 in. auger is a great choice.

Key Features:

• Diameter: 9 in.
• Height: 48 in.
• Bolt-on spiral tip
• 2 replaceable high carbon cutting teeth
• Capable of auguring a 4 ft. deep hole
• A heavy-duty auger bit is built to handle demanding conditions
• Ideal auger for 2 in. round drive post hole diggers
• Reinforced collar (takes two 1/2 in. diameter bolts at 90 degrees apart)
• 2 bolt-on heavy-duty cutting edges
• 9 in. Auger is used primarily on 3 pt. and skid steer diggers.
• Fits: All diggers with a 2" output shaft on the gearbox, such as Work Saver, Speeco, King Kutter, etc.

Benefits of 9 in. Heavy-Duty Auger for 3-Point Post Hole Diggers

A 9-in heavy-duty auger for 3-point post-hole diggers offers several benefits, making it a popular choice for various digging tasks. Here are some advantages of 9-inch auger bit:

1. Versatile Hole Size: The 9-inch diameter strikes a balance between smaller and larger augers, making it ideal for a range of applications like setting fence posts, planting trees, or installing structural supports. It’s wide enough to accommodate standard post sizes while still being manageable for smaller projects.
2. Enhanced Durability: Heavy-duty augers are typically constructed with thicker, reinforced steel and feature robust cutting edges, often replaceable or carbide-tipped. This design ensures they can withstand tough soil conditions, including clay, rocky terrain, or compacted earth, without bending or breaking.
3. Efficient Digging: Many 9-inch heavy-duty augers come with double flighting—two spiral blades instead of one—which increases cutting surfaces and speeds up the digging process. This is especially useful in heavier soils, as it helps move dirt out of the hole more effectively.
4. Compatibility with Tractors: Designed for 3-point hitch systems (often Category 1 or 2), this auger pairs seamlessly with a tractor’s PTO (power take-off), providing consistent power and torque. This makes it far more efficient than manual or handheld alternatives, reducing physical effort and time.
5. Deeper Penetration: With lengths typically around 36 to 48 inches, a 9-inch heavy-duty auger can dig deep enough for secure post installation or tree planting, often reaching depths of 41 inches or more, depending on the model and soil conditions.
6. Improved Soil Removal: The heavy-duty design, combined with a well-engineered spiral and sharp pilot point (like a fishtail or spiral tip), ensures better soil penetration and removal. This minimizes clogging and keeps the digging process smooth, even in loose or sandy soils.

Tractor 3-Point Post Hole Auger Bit Applications

A tractor 3-point post hole auger bit is a versatile tool designed to be attached to a tractor’s 3-point hitch and powered by its PTO (power take-off) system. It’s primarily used for digging cylindrical holes in the ground efficiently, making it a valuable implement for various agricultural, landscaping, and construction tasks. Here are some common applications:

The effectiveness of a 3-point post hole auger bit depends on factors like soil type (e.g., clay, sand, or loam), bit size (typically ranging from 6 to 24 inches in diameter), and tractor power.
